Abstract
An automatic control method suitable for a bicycle system is provided. The bicycle system has a gear ratio and a toque ratio formed by an auxiliary torque and a pedaling torque. The automatic control method includes following steps: sensing a pedaling cadence and the pedaling torque of the bicycle system in a riding state; setting a first cadence threshold and a second cadence threshold according to a preset pedaling cadence while the first cadence threshold is greater than the second cadence threshold; and determining whether the pedaling cadence is greater than the first cadence threshold or less than the second cadence threshold so as to set to increase or decrease the gear ratio. In addition, a bicycle system suitable for the automatic control method is also provided.
